A recent spate of shark attacks in waters off Western Australia has led to a "cultural shift" in surfing community nationwide, according to two-time world surfing champion Tom Carroll.

Carroll, who is in WA for the Margaret River surf pro, has signed on as an ambassador for Shark Shield - a company that is developing a surfboard fin system that incorporates its electronic shark repellent technology.

He said even professional surfers are thinking twice before going in the water.

The Australian public and its chefs are disconnected from the native plants and species around them, and should celebrate kangaroo as the country's national meat, according to a prominent Indigenous Western Australian.
